MHK1375CRBFD — MEIHUA(美华) 橙红发光二极管(插件式)

一、产品概述

MHK1375CRBFD 是美华(MEIHUA)出品的一款插件式发光二极管,发光色为橙红(波长 628nm),采用雾状红色透镜,发光均匀、视觉舒适。适合面板指示、状态提示、仪表显示与通用指示灯应用,封装为插脚式(引脚间距 P = 2.54mm),便于手工装配与快速原型开发。

二、主要参数

  • 发光颜色:橙红(红色/橙红调,λd = 628nm)
  • 正向电流(If):20 mA(典型工作电流)
  • 最大功率耗散:75 mW
  • 正向压降(Vf):2.05 V(在 If = 20 mA 时典型值)
  • 发光强度:30 mcd(在 If = 20 mA 时典型)
  • 发光角度:60°
  • 透镜:雾状红色透镜(光线柔和、眩光小)
  • 工作温度:-40 ℃ ~ +85 ℃
  • 封装:插件式,P = 2.54 mm
  • 品牌/型号:MEIHUA 美华 / MHK1375CRBFD

三、光电特性与实用计算

在典型工作点 If = 20 mA、Vf ≈ 2.05 V 时,器件实际耗电约为 41 mW(P = Vf × If),低于标称功率耗散 75 mW,留有一定裕量。常见电源下的限流电阻计算示例:

  • 5 V 电源:R = (5.00 − 2.05) / 0.02 ≈ 148 Ω,采用 150 Ω(1/4W)即可;电阻功耗约 0.06 W。
  • 12 V 电源:R = (12.0 − 2.05) / 0.02 ≈ 498 Ω,采用 500 Ω(1/2W)建议;电阻功耗约 0.20 W。

光强 30 mcd、视角 60° 表明本器件适合近距离或面板指示,非高亮远距离照明。雾状透镜有利于扩散光斑、减少点光源感。

四、封装与安装建议

  • 插件封装、引脚间距 P = 2.54 mm,便于插板、面板安装或自动插件装配。
  • 手工焊接建议:焊接温度控制在 ≤ 260 ℃,焊接时间尽量短(建议 ≤ 3 s),避免过热损伤半导体结。若进行波峰/回流焊,按厂方推荐的温度曲线执行或优先采用手工/插件后波峰方式。
  • 机械应力:避免在塑封体与引脚之间施加弯曲应力,装配时先固定引脚再焊接以减少应力传递。
  • 静电防护:在处理与装配过程中采取 ESD 防护措施(接地手环、抗静工作台),以免损伤器件。

五、典型应用场景

  • 仪表与面板指示灯(开/关、工作状态、告警等)
  • 家电与工业设备的状态显示
  • 消费电子与玩具的指示/装饰光
  • 原型开发与教学项目,因插件式便于替换与测试

六、存储与可靠性注意事项

  • 存放环境建议干燥、避光、避免高温(建议 ≤ 30 ℃)与高湿;长期存放建议使用防潮包装。
  • 使用前避免长时间暴露在强光或高温环境中,以免透镜老化或光输出下降。
  • 产品工作温度范围宽(-40 ℃ ~ +85 ℃),但在高温环境下应注意散热与连续工作电流限制,以延长寿命。

七、选型与采购建议

若需更高亮度或更宽视角,可参考同系列的高亮型号或不同透镜设计;若需要表面贴装(SMD)形式,请与供应商确认对应封装型号。采购时请注明完整型号 MHK1375CRBFD、所需数量及包装形式(散装/盘装),并索取数据手册以获取绝对最大额定值(反向电压、脉冲电流等)及焊接曲线,确保设计与可靠性满足项目要求。

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.

The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
